Forging a New Advanced Fuel Cycle Partnership
The advanced nuclear sector is witnessing a crucial integration of reactor design and fuel supply. Franco-Dutch startup Thorizon and leading uranium enrichment company Urenco have signed a memorandum of understanding (MOU) to explore a strategic partnership in the advanced nuclear fuel cycle. This agreement is specifically designed to evaluate Urenco’s role in the molten salt reactor (MSR) fuel supply chain.
Meeting the Unique Demands of Thorizon One
Thorizon is currently developing the Thorizon One, a 100 MWe small modular molten salt reactor. Unlike traditional light water reactors, Thorizon One operates on liquid fuel and has highly specific fuel requirements. It requires high-assay low-enriched uranium (HALEU) enriched up to 20% of the fissile U-235 isotope, delivered specifically in a molten salt form. Partnering with an established enricher like Urenco is vital to meeting these specialized demands.
By pairing Thorizon’s innovative liquid-fuel reactor design with Urenco’s extensive international enrichment infrastructure, the partnership aims to develop a robust domestic Western supply chain for next-generation nuclear systems.
Urenco's Capenhurst Facility and Future Production
A key component of this potential supply chain is Urenco’s Advanced Fuels Facility at Capenhurst in the United Kingdom. This facility is expected to begin producing HALEU by 2031. The collaboration also explores how depleted uranium can be repurposed as a viable fuel source for these next-generation systems, maximizing resource efficiency.
Backing and Development Milestones
Thorizon brings strong financial and governmental backing to the table. The company raised an additional €20 million in Series A funding in March 2025 and secured a €10 million French Government subsidy. Furthermore, in March 2024, it was selected as a winner of the 'innovative nuclear reactors' call under the France 2030 national investment plan. With these resources and the potential supply chain support from Urenco, Thorizon plans to deliver its first operational commercial reactor at Borssele in the Netherlands by 2034, driving significant HALEU demand in the European market.
